Therefore, this unit adopts the HDCP (High-bandwidth Digital Content Protection) system for copyright protection. This unit is also provided with a detection switch (TRAP switch) that will prohibit the unit from being turned on again if the rear case of the unit is opened, in order to prevent the panel technology from being leaked out.

    7.1.8 POWER ON/OFF FUNCTION FOR THE LARGE-SIGNAL SYSTEM Function: Only the power for the small-signal system (16.5 V, 12 V, and 6.5 V) is on, and the power for the large-signal system (VSUS, VADR) is off. Usage: 1. Use when only an operational check for the small-signal system is required, such as when making repairs. 2.

    7.1.9 BACKING UP THE ADJUSTMENT VALUES FOR THE MAIN UNIT Outline The data on the adjustment values for the main unit are stored in an EEPROM (IC5206, 4 kbits) on the DIGITAL VIDEO Assy. Part of the data (area A in the figure below) are automatically copied to an EEPROM (IC4002, 2 kbits) mounted on the PANEL IF Assy for backup.
